Can plants tell their location like GPS?

Do plants have a built in "GPS"? I know some have specialized hormones that can tell them about nearby dangers, like insects, etc. And Gravitropism tells them, using gravity, which way is up so they know how where to send the stem/roots. But I'm wondering if a plant has any ability to tell it things like direction (N, W, S, E), and/or perhaps distance.

    To a plant it won't use human compass direction but where the Sun rises, in the east, its path of travel through the sky, and where it sets in the west. It would use photophores or certain light detecting apparatuses to determine its position in relationship to the Sun's position, if that makes any sense.
